Analysis of offensive and defensive sports activities.
Analysis of Center position : Scoring and Performance Analysis
For this analysis, we focused on a general analysis of the following positions: Goal defender, Wing defender, Centre, Wing attack, Goal attack.
Clusters ?
NB : the activity data is expressed in number of offensive or defensive actions per match unit. The metrix have been relativised by the athletes’ playing time and expressed in count per match (4*15min) in order to facilitate the understanding of the values.
In view of the differences between the calculated “Gain” variable and the “Corrected Gain” variable which follows the basic evaluation calculation (sum of passes and shots). It seems relevant to consider the “Corrected gain” variable for the further analysis.
Graph 1 shows the groupings of athletes with dominantly defensive, dominantly offensive or mixed activities.
Graph 2 classifies the different athletes into three distinct clusters using the Kmeans method. The data appears to be grouped as “mixed activity”, “attack dominated activity”, “defence dominated activity”
profitability of the player in attack ?
This graph shows the balance between the player’s activity during the season, but also his efficiency. This allows us to determine which player has done the most work efficiently. In this case, we are concerned with evaluating the quality of our players on the offensive activity.
TOP 3: Price, Nankivell and Jovic, are the best performing players in the Kmean category “Mixed activity”,
TOP 3: Garbin, Fowler and Wallace, are the best performing players in the Kmean category “Attacking dominance activity”,
TOP 3: Mannix, Delaney and Sterling, are the best performing players in the Kmean category “Defending dominance activity”.
